WASTE AND REVENT marrine.

Application file'd March 2, 1911.

To all 'whom it may coiwem Be it known that I, JAMES Game, of Mlnneapolis, Hennepin County, Minnesota, have out in the claim.

invented certain new and useful Improvements in Waste and Revent Fittings, of which the following is a specification.

The object of my invention is to provide a fitting of very compact form and adapted particularly for use where the space is very limited, such as in a prison cell, for making the necessary connections.

A further object of my invention is to effect an economy of joints,-a fitting combining several fittings in one casting.

A further ob ect is to provide for increased rigidity of the sol stack, increasing the life of the plumbing and making leaky joints improbable and thereby insuring sanitary work.

A further object is to provide for re-venting close to the seals of the fixtures, thereby equalizing air pressure and causing a circulation of fresh air nearer to the fixtures than is possible in the ordinary system.

Further the invention. consists in various constructions and combinations, all as hereinafter described and particularly pointed In the acconpanying drawing forming part of this specification, Figure 1' is a vertical sectional view through a partition and floor, llustratin the application of my invention to the tolet fiXtures,'Fig-. 2 is aview showing the connection with the soil pipe and the vent pipes leading from the fitting to the pipe, Fg. 3 is a side view of the fittng, Fig. 4 is a top View, Fig. 5 is a vertical sectional View showing'the Construction of the fitting.

Tn the drawing, 2 represents a vertical partition, 3 a floor, 4 a seat fixture, and 5 a wash-bowl fixture.

6 is the sol pipe, arranged vertically near the partition wall, 7 is the vent, 8 is a secspecification of Letters Patent.

tion of the fittng inserted into the soil pipe n the usual way. This section is provided on one side with a branch 9 which extends upwardly and outwardly from the section 8 and terminates in a horizontal extension 10 to which the waste pipe ll from the seat 4 is connected. This branch is also provided with a hub 12 for connection with a pipe 13 which leads to the vent pipe 7. On the other side of the fitting section is a similar branch pipe 14 from which a pipe 15 extends to the vent and to which the pipe 16, leading from the bowl 5, is connected. With this fittng the connections with the fixtures may be made in a very limited space and the device is hence particularly well adapted for use in prsons, where there is very little room for making the necessary plumbing connections. The joints are reduced to a minimum and hence the connection will be more economical and will require less attention. Furthermore, the vent connections are close to the seals of the fixtures, causing a circulation of fresh air nearer to the fiXtures than usual in connections of this kind. Furthermore, the connection will brace and strengthen the soil stack and to a large extent prevent leaky joints.

I claim as my invention:-

The combination, with a soil stack, of a fitting inserted therein and comprising a pipe section and branch sections diverging therefrom, one of said branch sections having a horizontal extension for attachment with a seat fiXture, the other branch section having means for connection with a bowl fixture, a vent pipe, and pipes leading from said branch ppes to said vent pipe.

In witness' whereof, I have hereunto set my hand this 7th day of February 1911.
